hello here.

So one of my component java bean functions is not returning result I am expecting.

I added log.info to trace , doesn't print anything.

Then used debug from Eclipse , doesn't stop on breakpoints.

Where and what I should do?

Try this snippet of code.

Resource r = resourceResolver.getResource(path); Asset a = r.adaptTo(Asset.class); Rendition rnd = a.getOriginal(); long size = rnd.getSize();

Hi,

It is one of components Java bean class.

I access to the web page via WCM in localhost:4502 and I see the component, but the file size is shown as 0.00kb

ButI don't see any log.

I've used System.out.println("") too.

oh not mine was:

private final Logger log = LoggerFactory.getLogger(getClass());

I added this, compiled and deployed. but it is still not writing log.

should i restart?

So the bundle that contains your java code is empty?

Did you follow the guide[1] for adding Java classes to your OSGI bundle? It seems like your maven file has not been configured correctly to include the java class. After building you bundle, you should be able to unpack the jar file and see your class file.

Hi,

can you explain how the the URL you are calling will lead to your code being invoked? Are you calling the URL directly?

What kind of Java class is it?

It sounds as if you code is simply not being called. Doing things crudely, you should be able to see "System.out.println("");" statements if your code was being called.

Did you properly declare the logger:

/** Default log. */

protected final Logger log = LoggerFactory.getLogger(this.getClass());

the information is written to the aem log file too.

as far as I can see the core bundle is present in

http://localhost:4502/system/console/bundles

http://localhost:4502/system/console/osgi-installer

I need to show a DAM asset file size in 1 of my components.

So I pass here URL as for example /content/dam/project_name/<path>/filename.pdf

private int getFileSize(URL url) {
        HttpURLConnection conn = null;
        try {
           log.info(" URL : " + url.toString());
            conn = (HttpURLConnection) url.openConnection();
            log.info(" connected");
            conn.setRequestMethod("HEAD");
            conn.getInputStream();

            log.info(" input streem");

            return conn.getContentLength();



        } catch (IOException e) {
           e.printStackTrace();
            return -1;
        } finally {
            conn.disconnect();
        }
}
